The first participle “rooted” (perfect tense) indicates a settled condition on the part of the Colossian believers and refers to horticulture. The second participle “built up” (present passive) comes from the world of architecture. The third participle “firm [established]” (present passive) comes from the law courts.

The use of the passive probably reflects God’s activity among them. It was he who had rooted them, had been building them up, and had established them in the faith (cf. 1 Cor 3:5-15 for the use of mixed metaphors).
